Resuscitation with intravenous fluid can restore intravascular volume and improve stroke volume. However, in unstable patients, approximately 50% of fluid boluses fail to improve cardiac output as intended. Increasing evidence suggests that excess fluid may worsen patient outcomes. Clinical examination and vital signs are unreliable predictors of the response to a fluid challenge. We review the importance of fluid management in the critically ill, methods of evaluating volume status, and tools to predict fluid responsiveness.
静脉输液复苏可恢复血管内容量并改善心输出量。然而,在不稳定患者中,约50%的液体冲击未能按预期改善心输出量。越来越多的证据表明,过多的液体可能会使患者的预后恶化。临床检查和生命体征并不是预测液体冲击反应的可靠指标。我们综述了危重症患者液体管理的重要性、评估容量状态的方法以及预测液体反应性的工具。
